How to reproduce:
1. Open the “PrefabOverrideRetainIssue“ project
2. Open the “SampleScene”
3. Open the “Terraformer_TESTER“ Prefab in the Project window
4. In the Hierarchy select the “Left_Foot_IK” GameObject and in the Inspector add the “Rigidbody” Component
5. Save the Prefab and return to the scene
6. In the Hierarchy select the “Terraformer_TESTER“ GameObject
7. In the Inspector observe the Overrides list

Expected result: The Overrides list shows the “Rigidbody” Component of “Left_Foot_IK” GameObject
Actual result: The Overrides list is empty
